I built this set up for my brother but never overclocked his CPU. Wonder if I got him missing out on some extra horses.

Generally, the faster the CPU, the smaller the bottleneck. The overhead for GPU's increases with each additional GPU's so while two may be decent, there can still be some performance to be unlocked from overclocking the CPU.

Lol. Just Cause 2 crashed for me 2 minutes ago after receiving sandybridge stuff today. I guess the vastly increased gpu utilization made it cringe at last. Actually I think Just Cause 2 at maxed out levels (except medium shadows, medium ssao, 8xcsaa) is a great stability checker, as most things passed my tests at even the step below 1.088v.

Oh, well up to 1.1volts then (crosses fingers). At least I know the GTX580 IS indeed quite bottlenecked with a Q9550 running @ 3.5 ghz.

Are you running Firefox version 2/3 or 4? I ask, because FF 2/3 is a notorious memory leaker, in any case it may be worth either switching to FF4 or to Chrome and see if the leakage goes on.

FF 3, I tried 4 in the beta and was not too very fond of the interface....

I'll try reinstalling it later....i have traced it to a definite problem with memory usage...

I would get the Arctic Accelero Xtreme Plus cooler for that 580. I have one on mine, and it is great at low temps. Checkout my sig rig.

Here is proof of my GTX 580.

Max temps on my 580 are only 66C in benches which isn't life threatening. I just want to be able to OC this thing further. And I'm not sure an Accelero Xtreme with passive heatsinks on VRMS will do what I need it to.

I just ordered one for my GTX 580
